Good algae busters include Egeria densa, Brazilian pennywort, rotala rotundifolia, any hygrophila species but especially polysperma, corymbosa and difformis. I don't want to rag on you, but the algae problem could have probably been avoided if you followed this from the beginning. No worries, though, this is a learning process.
You just to get the CO2 back to a stable level, probably 30-35ppm if you can. I can't make any recommendations on cutting back the lighting. It works for some people and it probably wouldn't hurt, but I normally run my lights between 8-10 hours anyways, depending on my system, and I've never had to reduce it further than that.
Good luck to you, algae is yucky. Have no clue why marimo balls are so popular. Just more algae to me.
